Title: Method for recovering recombinant proteins
Inventor: MEHROTRA VIKRAM
IPC: C07K1/14
Filed: 1990-05-10
Abstract: A method for recovering a recombinant protein from a protein solution containing high molecular weight contaminating proteins by directly adding amine or quaternary ammonium compounds to the solution in amounts sufficient to selectively pre-cipitate the high molecular weight protein contaminants. The high molecular weight precipitates are removed and the solution is further processed to remove low molecular weight contaminating proteins and other non-protein contaminants.

Title: High performance polyurethane base resins
Inventor: HARTMAN TERRENCE L
IPC: C08G18/12
Filed: 1992-04-06
Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed are polyurethane base resins, and polyurethane composites  and adhesive compositions  formed using the base resins.  The polyurethane base resins are formed by reacting a polycarbodiimide-modified 4, 4'-diphenylmethane diisocyanate with a mixture of the following polyols:  (a)  a hydroxyl-terminated, linear,  saturated  liquid  copolyester  diol  having  a  glass transition temperature of at most -10°C and at least -60°C; and  (b)  a homopolyester polyol that is a ring-opened polymer of a cyclic ester.  The polyurethane composites include typical active hydrogen-containing species that will react with isocyanates and promote curing, in addition to the polyurethane base resin.  The polyurethane adhesive compositions, which are thermosetting, include the cured polyurethane base resin, cured by exposure to           moisture or any other applicable curing mechanism.  The adhesive compositions have improved performance (e.g.,  tensile strength  and  adhesion)  at  elevated  service temperatures, and are suitable for high performance automotive structural bonding applications.

Abstract: A method of forming a sheet of material with indicia thereon comprises applying indicia to the sheet by an electrostatic copying process in which a toner powder is deposited on the sheet and is healed to cause it to fuse. The sheet of material comprises a flexible support layer that is provided with a porous coating of a latent curable material, preferably in particulate and/or filamentary form and especially one based on an epoxy material. It has been found that the indicia are more indelible than those formed on other surfaces by the same process even though the fused toner is not absorbed by the curable material.

Title: Digital correction of vcr head skip for multimedia video capture devices
Inventor: RICKARD THOMAS W
IPC: G11B20/02
Filed: 1993-02-11
Abstract: ABSTRACT      This specification concerns signal processing apparatus for  processing  line  synchronization  pulses  in  a  line synchronization signal that define an analog video signal line period.  The apparatus comprises a phase locked loop (40) for generating a clock signal of a frequency that is a multiple of the line synchronization signal frequency. The phase  locked  loop  (40)  comprises  a  counter  (100)  for dividing the clock signal by said multiple.  The apparatus further comprises logic (110,50) for resetting the counter (100) upon detection of a spurious pulse introducing a time interval into the line synchronization signal of less than the  line  period  of  the  video  signal.  The  apparatus  is particularly  useful  in  image  processing  systems  for digitizing analog video signals that have been replayed via a conventional,  domestic video tape player,  and therefore may  comprise  spurious  line  sync  pulses  introduced  by playback head skip.

Title: Apparatus for accurately laying conduit within a trench and method of using the same
Inventor: CRANE LOWELL
IPC: E02F5/10
Filed: 1993-02-25
Abstract: ABSTRACT OF THE DISCLOSURE   An apparatus and method for laying conduit within a trench, using a separable boxlike structure with end walls, side walls, a fill bin compartment internal of the boxlike structure for receiving fill material and dispensing fill material onto the bottom of the trench, and a conduit laying compartment through which conduit is fed for positioning on the bottom of the trench. The boxlike structure has a rigidly mounted tow bar which facilitates application of vertical, longitudinal and lateral forces on the boxlike structure to thereby enable an operator of the apparatus to maneuver it on-grade and in alignment along the bottom of the trench. The boxlike structure is maintained on-grade and in alignment with the assistance of a laser transmitter/receiver assembly and several grade-maintenance features, including a shearing blade which automatically adjusts its vertical position in response to the laser. A reflecting mirror is provided on the boxlike structure for intercepting and reflecting a laser beam used for alignment downwardly into the apparatus toward the conduit being laid. A weighted pendulum maintains the mirror oriented to insure reflection of the beam in a vertical direction independently of the movements of the boxlike structure. In this way, an indicator or sensor in the immediate vicinity of the conduit can provide very accurate alignment information independently of the degree of tilt or excessive lateral shifts of the boxlike structure. When an obstacle is encountered, the boxlike structure may be separated into an upper portion and lower portion so that the upper portion can be unconnected and removed from the lower portion. The laying of conduit within the trench can continue using only the lower portion until it is clear of the obstacle and the upper portion can be repositioned on the lower portion. The apparatus may also have a dewatering system, a conduit setting system, and a system for dispensing fill material around the conduit and onto the bottom of the trench.
